Mauritania Trials New Substrates versus Polymer

To mark the 50th anniversary of the creation in June 1973 of the ouguiya (MRU) as the national currency of the West African state of Mauritania, the Banque Centrale de Mauritanie is issuing a commemorative MRU 50 banknote on not one but three different substrates.

The current series of circulating notes is on polymer, but in this commemorative version, two are on a composite substrate – Louisenthal’s Green Banknote based on Hybrid ADDvance, which has a paper core with a thin layer of polymer either side, and Landqart’s Durasafe, which has a polymer centre fused with an outer layer of paper either side. The third substrate is Highlink™ Sisal from Oberthur Fiduciaire, which is a cotton substrate reinforced with sisal.
